ok heres the skinny on it.
FIRST no offense taken but when you move just the upper arm mounts and not the lowers and dont change the length of the steering rack to match, you have a problem. that problem is the toe in will change from layed out to raised up. if you dont mind wearing tires and the toe being wrong thru 75% of the travel, go ahead and do that.
you dont have to be an engineer to figure that out either. just read a few books on suspension.
SECOND, the entire problem with the design of the Ranger is the mounts are very low in relation to the body of the truck. plus the Ranger spindle is very tall and causes the upper arm to lay over when layed out. so no matter what you do to the suspension in the stock form it will not completely fix the camber problem. you can have it perfect at ride height but layed out it will come in some and theres not muh you can do about that except replace the entire suspension with one that mounts much higher on the frame.
just raising the frame wont fix this either due to the amount you would need to raiseit to make it perfect, then the very tall Ranger spindle will kill you.
THIRD, jon, what the F do you know about my arms? ill tell ya nothing, there not like GJM arms, I had a set of DJM arms on Brandons Ranger and used the stock ones for my jig instead of the DJMs. the only thing I even did with the DJMs was look at the angle.
a smaller spindle would bring the arms together and allow for the upper arm to move more up and down and not so much in and out and help with the amount of camber change.
true.
but like I said before, the steering rack or drag link knuckles must fall in the line between the upper arm bushing and the lower arm bushing, if they do not the toe in changes during raising and lowering.
this will cause a truck to jump completely from one side of the road to the other.
if you email me ill email you back. but remember I have more than 100 emails every day and sometimes forget to reply or get back to people.
I have a book about suspension written by Boyd Coddington that shows suspension design, techinical info and rules of geometry that have to be followed.
you cant just go changing the upper arm mount to solve the camber issue because it creates a far bigger problem.
Im working on a way to run a Toyota spindle with a Ranger frame that may solve it as best as it can be solved with the frame in the stock location.
its just a matter of making the arms fit the ranger frame with balljoints for a Toyota. if all the angles and everything works out ill let someone test a set.
Brandon, your arms are the length they are because they cant be any longer or the wheels will hit the fender. the wheels need more offset and then the uppers could be longer. or the lowers could be shorter and help some.
